To all whom it may concern Be it known that I, Cosnnmus S. CLARK,

a citizen of the United States, residing at Norfolk,=in the county of Norfolk and State of Virginia, have invented new and useful Improvements in Filler-Blocks for Rails, of

. which the followingis a specification.

will not become readily displaced under traffic, and yet which in case of needed repairs to or replacement of'the rails can be readily removed.

In the drawings which accompany and form a part of this specification, I have illustrated several forms of my invention, all

embodying the same characteristic features,;

' the joint boX as shown.

, 'Where the block is used over a fish plate and in said draw1ngs Figure 1 is a transverse sectional view, parts being shown in elevation, of a roadbed to illustrate my new improved form of filler block. Fig. 2 is a view showing a slightly modified block. Fig. 3 is a similar view showing thebloek workedout in metal.

Fig. 4% is a plan view of a rail joint with the tread flange cutaway to show the form of block shown in Fig. 3. V

Referring to the drawings by numerals, like numbers indicating like parts in the several views, 10 indicates a rail of any standard or desired construction, characterized, as is customary, by a bed flange, a vertical web, and a tread flange. The rail 10 will, of course, be laid upon any suitable foundation, and the filler blocks which I have invented will then be utilized to fill in between the bed and tread flanges and against the vertical web.

Much difficulty is experienced in street railway bed construction in maintaining the paving adjacent the rails in good condition,

' the car trailic and vehicle traflic tending to displace these, and this naturally results in an uneven street surface. The filler blocks 7 Specification of Letters Patent:

the block 11 is chamfered off or inclined inwardly and downwardly as at 16 so that the grout or ballastlb'eneath the block surface will pack heavily and closely against this inclined face, and any downward pressure will tend to wedge the block 11 to its seat in the rail cavity.

Where the block is used adjacent a rail joint boX 17, as shown in Fig. 1, it will be formed as there. shown with a straight or inclined face at its bottom, and the offsetlB will engage a complementary recess 19 on it will be constructed similar to the block first described, except thatin adapting it to the fish plate the inner face of the block 20, as shown in Fig.2, will be channeled or grooved or recessed as at 21, so as to span the bolt heads and provide bearing lugs 22 which, will rest directly against the fish plate.

are designed to avoid The block 11 is fitted on one side i more closely In Fig. 3 I have disclosed my invention as worked out in metal, and instead of filling the rail cavity solidly with the block I provide the web '23 which engages at its top beneath the tread flange of the rail, and has at its bottom the foot 24 resting upon the bed flange, the web-at its lower portion being lnclined inwardly and downwardly to the foot to give the edging face referred to inconnection with the wooden block. In order to sustain the web against severe crushing strains I preferablyprovide it with a horizontally projecting strut which, as shown in Fig. 3,takes its bearing against the web of the rail and resists inward strains.

It will be understood that so far as design is concerned these blocks. will be varied in 1. A filler block for rails having a bed,
